"Their median family income is more than $73,000, compared with $66,000 for civilians, and recruits are most likely to come from families in the middle of the wealth distribution, with median wealth of $87,000, almost $10,000 more than civilians."
This is for enlisted members. It's probably safe to have some intuition that officers will skew wealthier.
